Testing boosts recall, study says

The simple act of taking a test helps you remember everything you've learned, even if it's not on the test, new U.S. research suggests.In a study of 84 undergraduate students, psychologists at Washington University in St. Louis found that untested students recalled significantly less of what they had studied — even after having extra time to go over the material.Researchers argue in the November issue of the Journal of Experimental Psychology that tests are more than efficient scoring tools. They are a "powerful memory enhancer."

Thanks for the memories: Testing boosts recall, study says
